PUMP.

SPECIFICATION forming part of Letters Patent No. 227,439, dated May 11, 1880.

Application filed March 8, 1880.

T 0 all whom it may concern:

Be it known that I, DAVID P. MANROSE, a citizen of the United States, residing at Riverton, in the county of Fremont and State of Iowa, have invented certain new and useful Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description of the invention, such'as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to letters or figures of referencemarked thereon, which forms a part of this specification.

My invention relates to lift-pumps; and it consists in a submerged pump of peculiar construction and arrangement of its operating parts, whereby it is enabled to lift water from deep wells with great facility and ease of operation.

My inventionis designed as an improvement upon Letters Patent of the United States No.

.B is provided with an ordinary weighted clack- 2l1,414, grant( (1 to me January 14, 1879, for improvement in pumps.

My present improvement consists more particularly in a submerged pump consisting of two cylinders, one of which is stationary and open at its lower end, and the other reciprocating, the latter or movable one, and which is open at both ends, working within the stationary cylinder, and having a disk-valve atone end and a screen at the opposite end, and operated by suitable rod and lever connections.

It further consists in combining with the pump-cylinders, as above described, ordinary gas or steam pipe having communication with the pump at its lower end, and its upper end, or point where the water is discharged, surmounted by an air-chamber, for the purpose of rendering the delivery of the water from the pump through the tubing uniform and continuous.

1n the drawing, Arepresents an upright, of wood or other material, to which the operating parts of the pump are attached; but they may be secured in any other suitable way.

B represents a fixed or stationary cylinder, entirely open at bottom, and surmounted by a valve, 1), and valve-box 1). Within cylinder B is fitted another cylinder, 0, so as to reciprocate therein by means of rod-and-lever 0011- (No model.)

nections. This cylinder C is open at both ends, and is provided at top with a valveseat, 0, and disk-valve D, secured at said top in the following manner: Abrace or rod, (1, is placed and secured diametrically across the upper end of the cylinder 0, and which carries a short upright rod, 6, having a cap or nut, f. Upon this rod 0 is placed the diskvalve D, it having a central opening for that purpose, and a free but limited vertical movement upon said rod between cap f and valveseat 0.

A cross-bar, E, is secured to the lower end of cylinder 0, and projects outwardly sufficiently far beyond cylinder B to receive the lower ends of the double plunger-rods F F.

A screen, G, of any suitable or known construction adapted for the purpose, is placed across the lower end of cylinder 0; but it may be dispensed with if desired.

The upper end or head of stationary cylinder valve, b, opening outwardly from the cylinder and inclosed by a valve-box, I), of any desired construction. This ValVG-bOX 1) receives the lower end of the conduit-pipe H, constructed of ordinary steam or gas pipe, surmounted by an air-chamber, I, having apump-spout, i, at its lower end. This air-chamber serves the purpose of rendering the supply of Water from the pump when in use continuous and uniform.

The double plunger-rods F F work in guideways secured to the side of cylinder B, and are fastened at their lower ends to the .projecting ends of cross-bar E, and at their upper ends to the cross-bar K. To the cross-bar K is secured the rod L, which in turn is fastene to the lever 0, to which the power is applied to operate the pump.

The operation of the device is as follows: Upon the lever being'raised the cylinder will move downwardly through its connection with plunger-rods F F L and cross-bar K. This downward movement of the cylinder raises disk-valve D from its seat and allows the Water forced into the cylinder by said movement to flowinto cylinder B. Upon the lever 0 being depressed it will raise the cylinder 0, the disk-valve seating itself by the pressure of water above it, and the water will beforced up through the pipe or tube H, the valve I) opening and allowing it to pass, but immediately closing upon the cylinder again being depressed and retaining the water in the pipe H. Upon being again raised and depressed the operation will be repeated, and so on indefinitely, the supply of water from the tube being rendered continuous and uniform when in operation by means of the air-chamber I.

Having described my invention, What I claim as new, and desire to secure by Letters Patent of the United States, is L 1. In a force'puinp, the stationary cylinder B, open at its lower end and provided at its upper end with the valve 1), in combination with reciprocating cylinder 0, openv at both Witnesses G. D.
